WATER CONNECTIONSCONNECTION TO THE WATER MAINS

! CAUTION!Always use a wrench and nose key for connection of the coil to thepipes (fig. 12). If the solenoid valve is installed, suitably insulatethe valve body with insulating material (fig. 13).Connect the water inlet and outlet pipes, observing the indications givenon the side of the appliance. Correctly insulate the water supply pipesto prevent dripping during the cooling mode of operation. An shutoffvalve should be inserted on the water supply pipe and balancing valveon the outlet pipe. The valve body and balancing valve should also beproperly insulated to prevent dripping. It is the installer's responsibilityto insulate properly and the manufacturer cannot be held liable for anyinsulation work.N. B.: It is always advisable to install the solenoid valve. In the heatingmode of operation the solenoid valve reduces consumption becauseupon reaching the set temperature the circulation of water is stoppedto avoid wasting energy (the fan coil would otherwise continue to heatlike a radiator, even with the motor at a standstill). In the cooling modeof operation the solenoid valve stops the circulation of water when theset temperature is reached, this stopiing the internal exchangerfrom continuing to condense water with possible undersirable drippinginto the floor. It also reduces chiller operation with consequent energysaving.

INSTALLATION! RECOMMENDATIONS FOR INSTALLATIONBefore installing the appliance, ensure that:1) the place of installation has sufficient space for carrying out installation

as well as routine and extraordinary maintenance work (see fig. 4).2) There are no obstructions for air intake and delivery.3) The water connections are of the sizes, in the position and spaced

apart as required by the appliance (see Dimension).4) The system pressure does not exceed 8 bar for the water versions.5) The electricity supply corresponds to the data on the appliance rating

plate and that there is a afety switch readily accessible to the user tocut off the power supply whenever necessary.

6) The safety switch is in the OFF position so that there is no voltageon the appliance supply line.

CONDENSATE WATER DRAINAGEThe condensate drain pipe should slope downwards by at least 3 cm/mand should not have ascending or throttled section in order to ensurea regular flow of water. It is advisable for a trap to be fitted. The condensatedrain pipe should be connected to a rainwater drainage system. Do notuse sewage system to avoid possible odours in the event of evaporationof the water in the trap. Upon completion of work, check that thecondensate flows out properly by pouring water into the tray (see fig. 14and 15). The condensate water drainage system should be fabricatedin a workmanlike manner and should be periodically checked. Themanufacturer cannot be held liable for any damage caused bydripping in the absence of a solenoid valve or of periodicTo replace the housing.

TURNING THE COIL! CAUTION! The fan may reach the speed of 1,000 rpm.

Do not insert objects or hands into the electric fan. The motor becomeshot during operation; wait for it to cool before touching it. During theheating mode of operation the exchanger and the connecting pipes maybecome very hot (80°C).Wait for the exchanger to cool before touching it or protect handswith suitable gloves. The heat exchange water coils are suitablefor working up to ma maximum pressure of 8 bar.To turn the coil, proceed as follows:

The power cables should be sufficiently long so that in the event ofaccidental tugging the active wires are subjected to stress before theearth wire. Connect the earth wire to the relative terminal marked withthe symbol . Check the earth connection. Comply with the safetyregulations in force in the country of installation.CONNECTIONS TO THE TERMINAL BLOCKS (without contol panel)The electrical connections should be made to the terminal block on theside of the appliance (fig. 17). Each terminal is identified by the label tobe found on the terminal block.CONNECTIONS TO THE TERMINAL BLOCKS (with contol panel)The electrical connections should be made directly to the control panel,as shown by the relative wiring diagram. If the control panel has anelectronic temperature sensor (NTC) this sensor will be powered bymains voltage (230Vac/1/50 Hz) and is therefore provided with doubleinsulation.

! CAUTION! FAILURE TO COMPLY WITH THE INDICATEDCONNECTIONS MAY CAUSE MOTOR BURNOUT!

ELECTRICAL CONNECTIONSRECOMMENDATIONS

! Before carrying out electrical connections, ensure that theelectricity supply to the supply line has been cut off, checking that theon-off switch is in the OFF position. Only qualified electricians shouldcarry out the electrical connections. Check that the mains supply issingle-phase 230 Vac/1/50 Hz (± 10%). Operating the appliance withvoltages outside the above limits could cause malfunction and rendersthe warranty null and void. The fan coil power supply line should be fittedwith at least a switch isolator in conformity with European standardEN60947-3. Make sure that the electrical system is suitable for providingnot only the working current required by the appliance, but also thenecessary current for powering household and other electrical appliancesalready in use. Any electrical and mechanical alterations or tamperingrender the warranty null and void. The motor and accessories powercables in channels or ducts should remain inside the same until they areinside the appliances.The cables should be sufficiently long so thatthey are not permanently taut or create throttling or pressure onmetal parts (see fig. 16).

CHANGING THE MOTOR SPEEDS OF ROTATIONThe fan coil motor has 6 speed settings, 3 of which are connected inthe factory (red, blue and black wires connected to the motor auto-transformer). To use other speeds than those wired up in the factory,the red (minimum), blue (medium) and black (maximum) wires may beconnected onto 3 of the 6 numbered terminals (1…6), taking into accountthat the speeds follow a sequence as shown in fig. 18

! * CAUTION!! UNDER NO CIRCUNSTANCES SHOULD THECONNECTIONS TO THE TERMINALS L, M, M BE CHANGED!!!
